Abstract: The photoluminescent properties of selected metal closo-boranes have been assessed. Group 3 elements Sc, Y, and La as well as Li, Na, and Eu-based B₁₀H₁₀²⁻ and B₁₂H₁₂²⁻ compounds displayed photoluminescence in the ultraviolet (emission λₘₐₓ≈ 350 nm) that ...

Abstract	The photoluminescent properties of selected metal closo-boranes have been assessed. Group 3 elements Sc, Y, and La as well as Li, Na, and Eu-based B₁₀H₁₀²⁻ and B₁₂H₁₂²⁻ compounds displayed photoluminescence in the ultraviolet (emission λₘₐₓ≈ 350 nm) that was not visible to the human eye, in contrast to previous reports. We attribute these earlier results to arachno-borane impurities, which are more readily observed due to their longer wavelength emission spectra.

Article ; Online: Measurement of signs of chemical shift differences between ground and excited protein states: a comparison between H(S/M)QC and R1rho methods.

Abstract: ... H(S/M)QC approach for measuring the signs of chemical shift differences. For the Abp1p and Fyn SH3 ... domains considered here it is found that while H(S/M)QC measurements provide signs for more residues ... frequently produces signs for more residues than when the H(S/M)QC method is used alone. ...

Abstract	Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion NMR spectroscopy has emerged as a powerful tool for quantifying the kinetics and thermodynamics of millisecond exchange processes between a major, populated ground state and one or more minor, low populated and often invisible 'excited' conformers. Analysis of CPMG data-sets also provides the magnitudes of the chemical shift difference(s) between exchanging states (\|Deltavarpi\|), that inform on the structural properties of the excited state(s). The sign of Deltavarpi is, however, not available from CPMG data. Here we present one-dimensional NMR experiments for measuring the signs of (1)H(N) and (13)C(alpha) Deltavarpi values using weak off-resonance R (1rho ) relaxation measurements, extending the spin-lock approach beyond previous applications focusing on the signs of (15)N and (1)H(alpha) shift differences. The accuracy of the method is established by using an exchanging system where the invisible, excited state can be converted to the visible, ground state by altering conditions so that the signs of Deltavarpi values obtained from the spin-lock approach can be validated with those measured directly. Further, the spin-lock experiments are compared with the established H(S/M)QC approach for measuring the signs of chemical shift differences. For the Abp1p and Fyn SH3 domains considered here it is found that while H(S/M)QC measurements provide signs for more residues than the spin-lock data, the two different methodologies are complementary, so that combining both approaches frequently produces signs for more residues than when the H(S/M)QC method is used alone.

Abstract	The paper mentioned in the title contains inaccuracies and misleading interpretations that seriously misrepresent basic knowledge about tautomerism in azo dyes. Therefore, we aim in this Letter to correct the most obvious mistakes, to address the misrepresentation of the main issues of tautomerism, and to give a better understanding of the basic principles of the tautomerisation process.

Abstract	Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion NMR spectroscopy has emerged as a powerful tool for quantifying the kinetics and thermodynamics of millisecond exchange processes between a major, populated ground state and one or more minor, low populated and often invisible ‘excited' conformers. Analysis of CPMG data-sets also provides the magnitudes of the chemical shift difference(s) between exchanging states (\|Δϖ\|), that inform on the structural properties of the excited state(s). The sign of Δϖ is, however, not available from CPMG data. Here we present one-dimensional NMR experiments for measuring the signs of ¹HN and ¹³Cα Δϖ values using weak off-resonance R ₁ρ relaxation measurements, extending the spin-lock approach beyond previous applications focusing on the signs of ¹⁵N and ¹Hα shift differences. The accuracy of the method is established by using an exchanging system where the invisible, excited state can be converted to the visible, ground state by altering conditions so that the signs of Δϖ values obtained from the spin-lock approach can be validated with those measured directly. Further, the spin-lock experiments are compared with the established H(S/M)QC approach for measuring the signs of chemical shift differences. For the Abp1p and Fyn SH3 domains considered here it is found that while H(S/M)QC measurements provide signs for more residues than the spin-lock data, the two different methodologies are complementary, so that combining both approaches frequently produces signs for more residues than when the H(S/M)QC method is used alone.

Abstract	A pair of chimeric twins, T.S. (male) and M.R. (female), were examined. The amounts of 'foreign' blood cells in each twin found on three occasions were compared. The percentages of M.R. cells found in the blood of T.S. in 1977 and in 1982 were similar and about 1/5 of that found in 1970. The amount of T.S.-blood cells found in M.R. was declining slowly from about 31% in 1970 to about 25% in 1982.

Abstract	IODP Site U1309 was drilled at Atlantis Massif, an oceanic core complex, at 30?N on the Mid-Atlantic Ridge (MAR). We present the results of a bulk rock geochemical study (major and trace elements) carried out on 228 samples representative of the different lithologies sampled at this location. Over 96% of Hole U1309D is made up of gabbroic rocks. Diabases and basalts cross-cut the upper part of the section; they have depleted MORB compositions similar to basalts sampled at MAR 30?N. Relics of mantle were recovered at shallow depth. Mantle peridotites show petrographic and geochemical evidence of extensive melt-rock interactions. Gabbroic rocks comprise: olivine-rich troctolites (> 70% modal olivine) and troctolites having high Mg# (82-89), high Ni (up to 2300 ppm) and depleted trace element compositions (Yb 0.06-0.8 ppm); olivine gabbros and gabbros (including gabbronorites) with Mg# of 60-86 and low trace element contents (Yb 0.125-2.5 ppm); and oxide gabbros and leucocratic dykes with low Mg# (< 50), low Ni (~65 ppm) and high trace element contents (Yb up to 26 ppm). Troctolites and gabbros are amongst the most primitive and depleted oceanic gabbroic rocks. The main geochemical characteristics of Site U1309 gabbroic rocks are consistent with a formation as a cumulate sequence after a common parental MORB melt, although (lack of systematic) downhole variations indicate that the gabbroic series were built by multiple magma injections. In detail, textural and geochemical variations in olivine-rich troctolites and gabbronorites suggest chemical interaction (assimilation?) between the parental melt and the intruded lithosphere. Site U1309 gabbroic rocks do not represent the complementary magmatic product of 30?N volcanics, although they sample the same mantle source. The bulk trace element composition of Site U1309 gabbroic rocks is similar to primitive MORB melt compositions; this implies that there was no large scale removal of melts from this gabbro section. The occurrence of such a large magmatic sequence implies that a high magmatic activity is associated with the formation of Atlantis Massif. Our results suggest that almost all melts feeding this magmatic system stays trapped into the intruded lithosphere.

Abstract	Introduction: The purpose of this study was to evaluate medical record data from the 2018-2020 Yukon Quest International Sled Dog race to examine injury patterns and risk factors for dogs competing in multi-day ultra-endurance events. Specifically, we summarized injuries and illnesses that resulted in canine athletes being removed ("dropped") from competition, and in orthopedic injuries diagnosed in both dropped and finished dogs. Methods: The records of 989 dogs that started the race were examined, but only records from dogs in teams that went on to finish the race were included, for a total of 711 records. Results and discussion: Three hundred and sixty five dogs (51.3%) were noted to have at least one abnormal finding in their veterinary medical record during the race. Orthopedic injuries were most common, and 291 injuries were ultimately diagnosed in 234 dogs (32.9%). Ultimately, 206 dogs (29%) were dropped from competition, for any reason. The most common reasons for dropping dogs were orthopedic injuries (156 dogs; 188 injuries), gastrointestinal illness (22 dogs), and cardiorespiratory disease (7 dogs). Most orthopedic injuries in dropped dogs occurred in the thoracic limb (

Abstract	Objective: To analyze perinatal risks associated with three distinct scenarios of fetal growth trajectory in the latter half of pregnancy compared with a referent group. Methods: This cohort study included women with singleton pregnancies that birthed between 32 Results: The final study cohort comprised 5319 pregnancies. Compared to the referent group, the adjusted odds of perinatal mortality were significantly increased in Group 2 (odds ratio [OR] 4.00, 95%CI 1.36-11.22) and Group 3 (OR 7.71, 95%CI 2.39-24.91). Only Group 3 had increased odds of stillbirth (OR 5.69, 95%CI 1.55-20.93). In contrast, infants in Group 1 did not have significantly increased odds of demise. The odds of an SGA infant at birth increased in all three groups but were highest in Group 1 (OR 111.86, 95%CI 62.58-199.95) and Group 3 (OR 40.63, 95%CI 29.01-56.92). In both groups, more than 80% of infants were born SGA, and nearly half had a birth weight <3 Conclusions: Assessing the fetal growth trajectory in the latter half of pregnancy can help identify infants at increased risk of perinatal mortality and birth weight <3
